Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049090, here are decompositions:

13 + 1049077 = 1049090
67 + 1049023 = 1049090
79 + 1049011 = 1049090
127 + 1048963 = 1049090
181 + 1048909 = 1049090
193 + 1048897 = 1049090
199 + 1048891 = 1049090
223 + 1048867 = 1049090

Showing the first eight; more decompositions exist.
